An 1 L aqueous solution contains 28.5 g of Fe(NO3)3, and 46.5 g CaCl2 and 17.6 g of Ca(HCO3)2. a) What ions will you find in solution ? b) (4 point) You want to separate the calcium from iron by addition of Na3PO4. The Ksp for Ca3(PO4)2 (s) is 1.3x10-32 and that for FePO4(s) is 1.0 x 10-22. Identify the precipitate that forms first. c) Is the separation successful?
